Is a QR Code Generator/Reader possible on the 84+?
« on: January 24, 2014, 05:47:47 pm »
Everyone knows what QR codes are, right? Like this:


Well, is it possible to generate and/or read them on the 84+?

The only way you'll get an 84+ to interpret a QR code, short of attaching a camera to it, is to type it in :P
Here's a link with more info on their structure: https://en.wikiversity.org/wiki/Reed%E2%80%93Solomon_codes_for_coders

YEah reading is impossible because calculators don't have a camera. Of course, it depends what you mean by reading, though. On some sites, you can upload images with a QR code and it reads them, so maybe some sort of converter could be done?

I guess you could make the user input the code pixel for pixel :P

The user could just convert the bitmap using ImageStudio or TI-Connect then load as 8xi on calc. :P

If someone could make a low-res pocket scanner for the 84+ you'd be able to scan in qr codes.

All good ideas, but I know of the method at thonky.com , and I don't know what the part with the polynomials would equate to.

It'd be cool to see. At least the generation part. The reading though would probably not be worth it because of how long it would take to manually enter all of the things. Maybe a calculator only QR code type? Like a QR code but with a different format.

Generator is quite doable. I saw someone doing one for Prizms.
